The group is part of Kagawa Prefecture and consists of 28 islands of various sizes. To the northwest, in Okayama Prefecture lie the Kasaoka Islands. The name derives from shioyaku (塩焼く) or shiowaku (潮湧く) both meaning boiling seawater to get salt. However, the name may also refer to rough water created by the confluence of tides that mix around the islands.
